Title: Methods of making single crystal intermetallic compounds semi conductors
IPC: C30B29/40
Filed: 1973-05-07
Abstract: 1430480 Growing single crystals SONY CORP 7 May 1973 [11 May 1972] 21595/73 Heading BIS A single crystal intermetallic compound semiconductor is grown in a crucible from the bottom of a melt while maintaining the distance from the growing surface of the crystal to the upper surface of the melt substantially constant. The melt is preferably kept substantially constant in depth during the growing process by the employment of a specific configuration of crucible. The same effect can also be obtained by adding further melt material to the crucible as the crystal grows. As shown in Fig. 3 single crystal gallium phosphide is grown in a crucible 2 contained in a sealed container 1. The crucible 2 contains gallium which is fused to form a melt 3 by means of furnace 4a while phosphorus 6 is present in the bottom of the container 1 and heated by furnace 4b. The temperature of the upper surface 3a of the molten gallium, e.g. at about 1200C, is below the m.p. of the GaP and the temperature at 'the lower end 2a of the crucible is held at a temperature lower than that of the upper end e.g. 1150C. The temperature of the phosphorous 6 e.g. 450C is such that the phosphorous has a vapour pressure which exceeds the decomposition pressure of the GaP to be produced. As phosphorous has a bp of 280C there is a very substantial vapour pressure of phosphorous in the container 1 which diffuses into the molten Ga through the exposed upper surface 3a to form GaP. The GaP diffuses into the fused Ga towards the lower temperature portion 2a where GaP forms as a single crystal. The crucible 2 used has a specific configuration comprising a lower portion 2b and a necked portion of reduced diameter 2c such that the necked portion has half the cross sectional area of the lower portion 2b. The value of half is selected since approx 2 cc of GaP is produced from 1 cc of Ga. As a result of this specific crucible configuration the Ga melt 3 above the GaP crystal 7 is always kept at a constant height during growth. In order to keep the temperature variation between the upper surface 3a of the melt and the upper surface of the crystal 7 substantially constant the crucible 2 can be lowered in the furnace during growth. A modified crucible incorporating a seed crystal can also be used.

Title: Improvements in or relating to modulators or demodulators as employed in carrier wave signalling systems
IPC: H04J1/08
Filed: 1938-07-22
Abstract: 517,329. Modulating and demodulating apparatus. TELEPHONE MANUFACTURING CO., Ltd., PADDLE, L. H., and DRAKE, B. July 22, 1938, No. 21833. [Class 40 (v)] The signal input to a modulator or demodulator network is supplied from a pentode valve whose anode impedance is high compared with the impedance of the network. The demodulator D has the signal applied to its input terminals 4, 5 from the pentode PV arranged with negative feed-back by means of resistance R4. The input impedance across terminals 4, 5 is arranged to be the optimum load for the valve and then the impedance seen when looking from the demodulator in the direction of the signal source is very high. By this means the effects of leakage of carrier, supplied to terminals 2, 3, caused by lack of balance of the demodulator are reduced. Resistances R1, R2 shunt the primary windings of the output transformer and maintain the output load of the demodulator substantially constant. An unloaded filter NRF which attenuates the higher frequencies feeds the output valve V which is provided with some negative feed-back by condenser C and resistance R3. In a modification, Fig. 2 (not shown), the demodulator is not loaded on the primary side of the output transformer but a resistive load network is connected before the input to the unloaded filter. It is stated in the Provisional Specification that an unloaded filter consisting of resistances and condensers may be placed between the output of valve PV and the input to the modulator or demodulator network. Specifications 504,300 and 508,087 are referred to.

Abstract: 1499667 Anti-skid braking systems GIRLING Ltd 28 April 1975 [18 May 1974] 22265/74 Heading F2F A control piston 16, 18 in an anti-skid braking system (Fig. 3) is normally biased by fluid (e.g. hydraulic) pressure in chamber 27 to a position in which brake pressure may be transmitted from a port 23 to a brake actuator piston 12. The piston 16 (as shown there are two pistons 16 in series) is spring-biased to the right and therefore moves to the right when a solenoid valve 25, responsive to a skid signal, is operated to vent the chamber 27. This closes the valve 22 and increases the volume of the brake fluid passages between the valve 22 and the actuator piston 12. The piston 12 is abutted by the rod 7 of a parking brake piston 4 normally held off by air pressure introduced at 28. This pressure is also used to bias the pistons 16, 18, but the flow path is cut off when the solenoid valve 25 is operated. A line 24 leads to the slave cylinder of another brake. The system is shown only schematically in Fig. 3; the two pistons 15 are preferably mounted one on either side of, and at right angles to, the piston-rod 7, as indicated in Fig. 2.

Suitable dyes also include those containing methylol or etherified methylol groups preferably attached by way of nitrogen and which are applied together with an acid donor.  Suitable components (a) are described in Specifications 882,743 and 916,698 and are especially the methylol compounds of glyoxalmonoureine, glyoxaldidureine, butanediol-diurethane and the alkyl derivatives of the triazinones. The copolymers (b) are prepared from monomer mixtures containing especially N-methylol acrylamide or N-methylolmethacrylamide and methyl, ethyl, propyl or butyl acrylate by the method described in German Specification 1,047,431.  Further copolymers are described in Specifications 882,743 and 916,698.
